Pseudomonas atlantica

The pH-dependence of metal sorption by bacteria can vary significantly with metal concentration. For example, the sorption of Pb by Pseudomonas atlantica at the highest metal concentration (5x10-6 M) was almost independent of pH, whereas sorption markedly increased with pH when the metal concentration was low (Ledin 2000). On the other hand, the accumulation of Cd by Pseudomonas cepacia showed an increased pH dependence with increasing metal concentration (Savvaidis et al. 1992). The pH dependence may also be influenced by ionic strength.
